Suction device/blower

Abstract

A manually-guided, portable suction device/blower is provided, and includes a blower unit having a motor for driving the blower unit, a blower tube that extends from the blower unit, a collection bag, wherein during suction operation of the suction device/blower, the blower tube opens out into the collection bag, and a potential-equalizing device disposed within the collection bag, wherein the potential-equalizing device is electrically conductively connected with an electrical ground connection of the suction device/blower.

1. A manually-guided, portable suction device/blower, comprising:
 a blower unit having a motor for driving the blower unit; 
 a blower tube that extends from the blower unit; 
 a collection bag, wherein during suction operation of said suction device/blower, said blower tube opens out into said collection bag; and 
 a potential-equalizing device disposed within said collection bag, wherein said potential-equalizing device is electrically conductively connected with an electrical ground connection of said suction device/blower. 
 
   
   
     2. A suction device/blower according to  claim 1 , wherein said potential-equalizing device has a flexible configuration. 
   
   
     3. A suction device/blower according to  claim 2 , wherein said potential-equalizing device is an arrangement of electrically conductive threads. 
   
   
     4. A suction device/blower according to  claim 3 , wherein said electrically conductive threads are metallic threads. 
   
   
     5. A suction device/blower according to  claim 3 , wherein said collection bag is produced from woven material that includes said electrically conductive threads. 
   
   
     6. A suction device/blower according to  claim 1 , wherein said potential-equalizing device is embodied as an electrically conductive, film-like coating of said collection bag. 
   
   
     7. A suction device/blower according to  claim 1 , wherein said electrical ground connection is formed by said motor. 
   
   
     8. A suction device/blower according to  claim 7 , wherein said electrical ground connection is formed by a housing of said motor. 
   
   
     9. A suction device/blower according to  claim 8 , wherein a potential-equalizing conductor is provided and extends from said potential-equalizing device to said housing of said motor on the inside through a discharge elbow, and wherein an end of said potential-equalizing conductor that is in the vicinity of said motor is secured to said motor inside said blower unit in a region of said discharge elbow. 
   
   
     10. A suction device/blower according to  claim 9 , wherein said end of said potential-equalizing conductor that is in the vicinity of said motor is secured to said motor via a motor mounting bolt. 
   
   
     11. A suction device/blower according to  claim 1 , wherein a further potential-equalizing device is disposed in said blower tube, and wherein sad first mentioned potential-equalizing device is electrically conductively connected with said further potential-equalizing device.
